Hewlett-Packard Application Notes


Introduction by John Minck

In a real sense, Hewlett-Packard sold MEASUREMENTS as well as products. According to one marketing professional, when you go to a hardware store to buy a 5mm drill bit, what you really want is a 5mm hole. So, likewise, as HP developed their massive line of innovative measurement instruments, the customers often had to be educated in the newer processes of the new measurement techniques, permitted by the newest product.


In-depth discussions of important techniques developed by HP engineers and written by them are published in the Hewlett-Packard Application Note Series. In the HP numbering and archiving strategy, Application Note titles were assigned to generic measurement tutorials, which might cover multiple instrument numbers.
Another category of technical notes were called Product Notes. Product Notes were instrument-specific and although a wide range of topics were permitted, in general, PNs expanded on instrument performance characteristics beyond the Technical Data Sheet of product descriptions and specs.

Application Notes (even old ones) are being posted by the Agilent Technologies Company. Starting from the Agilent's web site home page, select "Technical Support" and "Application Notes" then, filling the search box with the AN number you are looking for, you can get results that include vintage application notes.

You will find below a listing of the original paper edition of Hewlett-Packard Application Notes available in our collection. Lines appearing in blue in the listing are links to the PDF files of the scanned original Application Notes. Most of these scans are homemade ! They are not copied from other sources on the Web. Scans are made at a resolution sufficient to allow good printing quality, and the shape and colors of the original document are preserved. New scans are added from time to time, mainly when the covered subject is important to the publication of a new chapter of the web site. We also have frequent requests from visitors searching for a vintage HP Application Note. We are always pleased to help for serious work. So, don't hesitate to ask, if the AN you are searching is listed below, we have the original. Just fill in the form on the Contact Us page.

The listing gives the following information:

  • AN-Nbr - The original numerical classification made by HP.
  • DATE - When their is one appearing somewhere in the application note.
  • Related Instr - The instrument for which the application note has been edited (if any). Or the
    instrument typical of the AN subject. XX number completion is frequently used and
    the "++" notation stand for "reference to the overall product line of the instrument listed"
  • TITLE - The exact title and sub-title if any of the application note.
